Definitions
- the invention relates to a bushing that permits a brake rotor secured by bolts to thermally expand while protecting the brake rotor from deformation by the compressive impact of the bolts acting on the rotor.
- Friction brakes are used in cars, trains, airplanes, elevators, and other machines.
- a driver steps on a brake pedal.
- the brake rotor is fixed to the hub of a vehicle axle by an array of drive pin/bolt combinations radially distributed about the axle.
- Each drive pin/bolt combination is placed through opposite ends of apertures in the brake rotor and the hub.
- the brake rotor and the hub are secured to one another by tightening each bolt into its counter part drive pin.
- each slot permits the brake rotor to expand and contract radially with the change in temperature of the brake rotor.
- the width of each radially slot works to control the rotational and axial movement of the brake rotor relative to the bolts and the brake pads.
- a larger problem with the heating of a brake rotor is fading.
- the temperature of the brake rotor increases, the rotor reaches a temperature where materials performance is adversely affected. As the rotor reaches this temperature, the frictional force between the brake pads and the brake rotor decreases. This phenomenon is called fading. Minimizing or preventing fading drives brake designers to focus on design techniques that dissipate brake rotor heat.
- Brake rotors are conventionally constructed from a variety of materials, including steel, cast iron, various metal alloys and composite materials.
- brake rotor designers look for toughness, low density (low weight), low wear, and high coefficient of thermal conductivity in the material they select for the brake rotor.
- brake rotors are cast in iron.
- new materials have been developed that allow casting of rotors from an aluminum metal matrix composite (MMC) material such as 359 aluminum with twenty percent silicon carbide particulate reinforcement. See, for example, U.S. Pat. No. 5,407,035 and U.S. Pat. No. 5,526,914.
- MMC aluminum metal matrix composite
- each slot width in one radial direction usually predominates over the deformation of each slot width in the opposite radial direction.
- the brake rotor freely begins to move rotationally relative to the bolts and the brake pads. Now, the width of each radially slot does not work to control the rotational movement of the brake rotor relative to the bolts and the brake pads.
- the present invention relates to a rotor assembly.
- the rotor assembly includes a rotor having rotor holes disposed about an axis.
- Bushings are disposed within the rotor holes in order to protect the rotor holes from compression impact deformation.
- Each bushing includes an internal slot that permits the rotor to radially expand and contract due to changes in the temperature of the rotor.
- a hub having pin holes that align with the rotor holes is held to the rotor by drive pins disposed within the pin holes and the bushings.
- a bolt is placed into the drive pin and tightened to fix the hub to the rotor in the axial and circumferential directions.
- FIG. 1 is an exploded isometric view of conventional brake rotor assembly 100 ;
- FIG. 2 is a plan view of FIG. 1 looking down on brake rotor assembly 100 without bolts 140 ;
- FIG. 3 is a cross sectional view of assembly 100 taken generally off of line 3 — 3 of FIG. 2;
- FIG. 4 is an exploded isometric view of rotor assembly 400 ;
- FIG. 5A illustrates a side view of busing 460 ;
- FIG. 5B is a top view of bushing 460 ;
- FIG. 5C is an isometric view of bushing 460 ;
- FIG. 6 illustrates bushing 660 brought about drive pin 430 as assembly 600 having rotor 410 and hub 420 removed for clarity;
- FIG. 7 illustrates bolt 440 brought into drive pin 430 as assembly 700 . Note how washer 450 may reside flat on top of cap 662 ; and
- FIG. 8 is a section view of assembly 700 as taken off of lines 8 — 8 of FIG. 7 .
- FIG. 1 is an exploded isometric view of conventional brake rotor assembly 100 . Included with brake rotor assembly 100 may be rotor 110 , hub 120 , drive pins 130 , bolts 140 , and washers 150 . As shown, rotor 110 is an annular ring having slots 112 disposed on the interior of the ring. Slots 112 are used to connect rotor 110 to hub 120 and yet allow for thermal expansion of rotor 110 .
- Hub 120 is an annular disc that includes axle hole 122 and pin hole 124 .
- Axle hole 122 is where an axle of an automobile might extend into so as to maintain rotor 110 adjacent to the brake pads and tire of the automobile.
- Drive pins 130 have a threaded interior and are extended through pin holes 124 and slots 112 so as to bring hub 120 in contact with rotor 110 .
- Washers 150 are inserted around bolts 140 and bolts 140 are threaded into drive pin 130 . Tightening bolts 140 into drive pins 130 fixes hub 120 to rotor 110 in the rotational and axial directions, but frees rotor 110 to expand in the radial direction.
- FIG. 2 is a plan view of FIG. 1 looking down on brake rotor assembly 100 without blots 140 .
- drive pin 130 resides within slot 112 at the furthest radially location within slot 112 during initial assembly. This makes sense since as rotor 110 radially expands die to heat, slots 112 move away from axle hole 122 and radially around drive pins 130 .
- FIG. 3 is a cross sectional view of assembly 100 taken generally off of line 3 — 3 of FIG. 2 .
- drive pin 130 resides within slot 112 at the furthest radially location within slot 112 , here the furthest point to the right of slot 112 in FIG. 2 .
- the compressive force of each drive pin 130 acting on its associated circumferential slot width 116 works to circumferentially distort the soft, malleable material forming each slot 112 , especially in high speed/temperature applications.
- the invention overcomes this through the use of a bushing such as illustrated in FIG. 4 and FIGS. 5A, 5 B, and 5 C.
- FIG. 4 is an exploded isometric view of rotor assembly 400 .
- rotor assembly 400 may be rotor 410 , hub 420 , drive pins 430 , bolts 440 , washers 450 , and bushings 460 .
- Rotor 410 may be based on an automobile brake rotor. However, rotor 410 is not limited to automobile brake rotors.
- Rotor 410 may be any annular disc or ring that (i) revolves with respect to a stationary part, (ii) heats up as the annular disc slows down with respect to the stationary part, and (iii) radially expands as the annular disc heats up.
- one way rotor 410 may heat up includes controlled slippage such as experienced by brake pads applying friction to the sides of rotor 410 .
- rotor 410 includes holes 412 .
- Holes 412 represent material removed from rotor 410 and are used to connect rotor 410 to hub 420 . Since round holes are the easiest to machine in an aluminum metal matrix composite (MMC) material, preferably holes 412 have a constant diameter.
- MMC aluminum metal matrix composite
- the interior profile of holes 412 is not limited to round holes.
- the interior profile of holes 412 may be any shape that is complementary to the exterior profile of bushing 460 , including holes in the shape of slots.
- the interior profile of holes 412 may be complementary to the exterior profile of bushing 460 so as to retain bushing 460 and also permit radial thermal expansion of rotor 410 , even where bushings 460 themselves permit thermal expansion of rotor 410 .
- Hub 420 preferably is an annular disc that may include pin holes 424 and axle hole 422 . Hub 420 may couple rotor 410 to a rotating piece (not shown) disposed within axle hole 422 .
- axle hole 422 is where an axle of an automobile might extend into so as to maintain rotor 410 adjacent to the stationary brake pads and rotating tire of an automobile.
- Assembly 400 preferably includes a locking pin such as a drive pin/bolt combination.
- Drive pins 430 have an interior or exterior by which bolts 440 may be fixed.
- drive pins 430 may have a threaded interior to fix exterior threads on bolt 440 or a threaded exterior to fix interior threaded bolt 440 .
- Bolts 440 preferably are threaded bolts, but may be any device performing a key or lock function in connection with drive pin 430 .
- Washers 450 include any flat, thin, continuous or discontinuous ring or perforated plate used in assemblies to ensure tightness or relieve friction.
- Bushings 460 are discussed in more detail in connection with FIGS. 5A, 5 B, and 5 C.
- bushings 460 are placed into holes 412 so that the long axis of slot 480 is aligned to a radial axis of rotor 410 .
- Drive pins 430 are extended through pin holes 424 and bushings 460 so as to bring hub 420 in contact with rotor 410 .
- washers 450 preferably inserted around bolts 440 , bolts 440 may be threaded into drive pin 430 .
- rotor 410 becomes fixed to hub 420 in the rotational and axial directions, where bushings 460 free rotor 410 to expand in the radial direction.
- FIG. 5A illustrates a side view of bushing 460 .
- FIG. 5B is a top view of bushing 460 and
- FIG. 5C is an isometric view of bushing 460 .
- Bushing 460 may be any lining between drive pin 430 (or bolt 440 ) and hole 412 that (i) protects holes 412 from compression impact, (ii) maintains the structural integrity of drive pin 430 (or bolt 440 ), (iii) works to retain rotor 410 from moving in the rotational and axial directions, and, (iv) in the radial direction, permits rotor 410 to expand on heating and contract on cooling.
- Bushing 460 may be part of rotor 410 or, preferably, a separate piece added to rotor 410 so that bushing 460 is removable from hole 412 .
- Retaining bushing within hole 412 may be achieved by any technique that lends itself to convenient assembly.
- bushing may be pressed or shrunk fit within hole 412 .
- Press fits are a function of interference fits whereas shrink fits may be accomplished by heating rotor 410 or by chilling bushing 460 in a mixture of dry-ice and alcohol, or in liquid air, prior to installing bushing 460 into rotor 410 .
- interlocking extensions between hole 412 and bushing 460 are preferred so as to key rotor 410 and bushings 460 together.
- bushing 460 preferably include ridges 462 distributed around exterior profile 464 of bushing 460 .
- Ridges 462 may be angular features that expand in a sixty degree angle as they extend radially inward approximately one millimeter towards the smooth surface 466 of bushing 460 .
- ridges 462 preferably include leads 468 having tapered portion 470 .
- tapered portions 470 blend into smooth surface 466 at a ten degree angle over the last three eighths of the length of ridges 462 .
- Smooth surface 466 may have a lead-in feature itself.
- bushing 460 may include other keying techniques such as employing one or more set screws, woodruff keys, bolted bearing flanges, exterior threads, dowel pins, and a housing cap.
- each hole 412 comprises two separate half (one being a cap) that are brought together to form a hole.
- Exterior profile 464 of bushing 460 preferably is round so as to permit a snug fit within hole 412 .
- exterior profile 464 may be any shape, including square, rectangular, oval, ellipse, and triangular as well as unsymmetrical shapes.
- the unsymmetrical shape may be ones that account for compressive impact and the need to secure bushing 460 to hole 412 .
- Bushing 460 may also include stepped portion 472 and slot 480 .
- Stepped portion 472 permits washer 450 to extend from bushing 460 across stepped portion 472 to rotor 410 at a flat level.
- Slot 480 may be of similar profile as existing slot 112 .
- sides 482 of slot 480 that pass through a radius extending from the center of rotor 410 are flat.
- Sides or flat surfaces 482 face one another so as to form width 484 as seen in FIG. 5 B. Since it is the fit between drive pin 430 and width 484 of bushing 460 that preferably retains rotor 410 from moving in the rotational and axial directions, it is important that width 484 be constant so that flat surfaces 482 are parallel to one another.
- a preferred technique of countering the compressive impact force of drive pin 430 is to select a hard material for bushing 460 .
- bushing 460 protects holes 412 from compression impact and yet maintains the structural integrity of drive pin 430 (or bolt 440 , which ever is external to the other)
- bushing 460 is made of a material having a Rockwell hardness number of approximately 36 to 50 on the Rockwell C scale (preferably Rockwell C-46). Note that the Rockwell C scale is for materials harder than Rockwell B-100.
- Bushing 460 preferably is made of a sintered metal material.
- a non-preferred technique of countering the compressive impact force of a drive pin onto the holes in the rotor is to reduce the force per unit area experienced by slots 112 of FIG. 1 .
- bushing 460 may be omitted.
- the force per unit area experienced by slots 112 of FIG. 1 may be reduced by at least one of increasing the length of slot 112 in the axial direction, by increasing the diameter of drive pin 130 and the corresponding circumferential width of slot 112 , and by angling slot 112 (so as to create more surface area). Since these techniques are not commercially practicable, they are non-preferred techniques.
- FIG. 6 illustrate s bushing 660 brought about drive pin 430 as assembly 600 having rotor 410 and hub 420 removed for clarity.
- Bushing 660 is similar to bushing 460 of FIG. 5 C.
- bushing 660 of FIG. 6 further includes a cap 662 that takes the place of stepped portion 472 as best seen in FIG. 5 A.
- drive pin 430 may reside to one side of slot 680 so as to leave room for movement between drive pin 430 and bushing 660 .
- FIG. 7 illustrates bolt 440 brought into drive pin 430 as assembly 700 .
- washer 450 may reside flat on top of cap 662 .
- FIG. 8 is a section view of assembly 700 as taken off of lines 8 — 8 of FIG. 7 .
- bushing 660 is placed into hole so that ridges 462 wedge into the sides of hole 412 of rotor 410 , with the material of rotor 410 tending to fill the spaces between ridges 462 so as to create a very secure fit.
- Drive pin 430 is placed through pin hole 424 , the assembly of which is brought into contact with rotor 410 so that drive pin 430 extends through slot 680 of bushing 660 .
- washer 450 placed about the shaft of bolt 440 , bolt 440 is tightened into the internal threads of drive pin 430 to a predetermined torque value so as to complete assembly 800 .
